[Introduction to our 304 stainless steel pipe and 316L stainless steel pipe]
Introduction to 304 stainless steel pipe: It is a kind of high alloy steel that can resist corrosion in the air or chemical corrosion medium. 304 stainless steel pipe is a kind of steel with beautiful surface and good corrosion resistance. It does not need surface treatment such as color plating, but gives play to the inherent surface properties of stainless steel, and is used in many aspects of steel.
304 stainless steel pipe is usually called stainless steel. The representative properties are 13 chrome steel, 18-8 chrome nickel steel and other high alloy steels. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface. This film is separated from the invading oxygen in the steel and plays a corrosion resistant role. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium. 304 is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to American ASTM standards. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China.
304 stainless steel performance: 304 stainless steel is a widely used chromium nickel stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. It has good processability and weldability.
Use of 304 stainless steel pipe: (1) civil pipe is divided into round pipe, rectangular pipe and flower pipe, which are generally used for decoration, architecture, structure and other aspects;
(2) Industrial pipes: steel pipes for industrial piping, steel pipes for general piping (drinking water pipes), mechanical structure/fluid conveying pipes, boiler heat exchange pipes, food hygiene pipes, etc. It is generally used in various industrial fields, such as petrochemical industry, paper making, nuclear energy, food, beverage, and other industries, which have high requirements for fluid media.
[Introduction to 316L stainless steel pipe]
Chemical composition of 316L stainless steel pipe material% (carbon) C ≤ 0.03 (silicon) Si ≤ 1.00 (manganese) Mn ≤ 2.00 (phosphorus) P ≤ 0.035 (sulfur) S ≤ 0.03 (nickel) Ni: 10.0-14.0 (chromium) Cr: 16.0-18.0 (molybdenum) Mo: 2.0-3.0 annealed solid solution state, 2B, N0.4, HL and other surface states
316L is a molybdenum containing stainless steel. Because the steel contains molybdenum, its overall performance is better than 310 and 304 stainless steels. Under high temperature conditions, when the concentration is lower than 15% or higher than 85%, 316L stainless steel has a wide range of uses. 316L stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment. The large carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be carried out after welding and where greater corrosion resistance is required
Use of 316L stainless steel pipe
Equipment for pulp and paper making: heat exchanger, dyeing equipment, film processing equipment, pipes, materials used outside buildings in coastal areas, watch chains and watch cases of advanced watches. Equipment for seawater, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.

Now let's understand the classification of stainless steel pipes:
[Stainless steel pipe is divided into three series: decorative stainless steel pipe, stainless steel product pipe and industrial stainless steel pipe]
Decorative stainless steel pipe: usually the outer wall will be bright pipe, so it is called Sixi. Decorative stainless steel pipe is used for decoration. Due to the different manufacturing process from industrial stainless steel pipe, the price is also very different. Generally, the production process of decorative stainless steel pipe is welding stainless steel pipe.
Stainless steel product pipes: generally, the surface of stainless steel product pipes is also bright, and a small number of pipes with pickling industrial surface will be found. As mentioned above, stainless steel product pipes belong to the purpose of stainless steel products. Because the outer diameter, mechanical properties, acid and alkali resistance, and corrosion resistance of stainless steel pipes are relatively good, the anti-corrosion materials commonly used by large chemical production enterprises are, Or for hardware products, stainless steel product pipes have strict requirements on outer diameter and wall thickness. The production process of stainless steel product pipes is one-time molding, and nitrogen protection is also added during welding.
Industrial stainless steel pipe: generally, the surface of industrial stainless steel pipe will be pickling pipe, and a small number of industrial stainless steel pipe will have black skin pipe. As mentioned above, industrial stainless steel pipe is for industrial use. Because stainless steel pipe has good acid and alkali resistance and corrosion resistance, generally the anti-corrosion materials used by large chemical production enterprises are stainless steel pipes, and the production process of industrial stainless steel pipe is one-time molding, It belongs to seamless stainless steel pipe.
Industrial stainless steel pipes are widely used to transport fluids, such as oil, natural gas, water, gas, steam and other industries.
In general, the price of industrial stainless steel pipe of the same material is higher than that of decorative stainless steel pipe, because of the production cost and the cumbersome process.
